Since the days of the first acknowledged microscopist, Antonie van Leeuwenhoek, the 'animalcules', that is, bacteria and other microbes have been subject to increasingly detailed visualization. With the currently most sophisticated molecular imaging method; cryo electron tomography (Cryo-ET), we are reaching the milestone of being able to image an entire organism in a single dataset at nanometer resolution. Cryo-ET will enable the next revolution in our understanding of bacterial cells, their ultra-structure and intricate molecular nanomachines. Here, we highlight recent research discoveries based on constantly progressing technology developments. We discuss advantages and challenges of using Cryo-ET to visualize spatial structure of microorganisms and macromolecular complexes in their native environment.

Background: Viruses that infect prokaryotes (phages) constitute the most abundant group of biological agents, playing pivotal roles in microbial systems. They are known to impact microbial community dynamics, microbial ecology, and evolution. Efforts to document the diversity, host range, infection dynamics, and effects of bacteriophage infection on host cell metabolism are extremely underexplored.

SARS-CoV-2 is the viral pathogen responsible for COVID-19. Although morbidity and mortality frequently occur as a result of lung disease, the gastrointestinal (GI) tract is recognized as a primary location for SARS-CoV-2. Connections and interactions between the microbiome of the gut and respiratory system have been linked with viral infections via what has been referred to as the 'gut-lung axis' with potential aerodigestive communication in health and disease.

BCG remains the only licensed vaccine for tuberculosis (TB), but its efficacy wanes over time. Subunit vaccines, aim to improve BCG immunity and protection, by inducing responses to a few mycobacterial antigens delivered with a specific platform. Since the platform shapes the immune response induced, selecting the right platform has been challenging due to the lack of immune correlates of protection.

Biofilms are critical in the persistence of Pseudomonas aeruginosa infections, particularly in cystic fibrosis patients. This study explores the adaptive mechanisms behind the phenotypic switching between Small Colony Variants (SCVs) and revertant states in P. aeruginosa biofilms, emphasizing hypermutability due to Mismatch Repair System (MRS) deficiencies.
